Maris Aqua/Sea Water/Eau De Mer ●
TL;DR. This ingredient functions mainly as the water phase, diluent, and mineral source in formulas. It can also support skin feel through dissolved electrolytes rather than acting as an active treatment.
What does Maris Aqua/Sea Water/Eau De Mer do in a cosmetic formula?
This ingredient functions mainly as the water phase, diluent, and mineral source in formulas. It can also support skin feel through dissolved electrolytes rather than acting as an active treatment.
Is Maris Aqua/Sea Water/Eau De Mer clean?
This ingredient is generally well tolerated and has little clean-standard friction. High mineral-salt content can sting compromised skin or feel drying in some formulas, but it is not a common allergen or major restricted-list issue.
Is Maris Aqua/Sea Water/Eau De Mer sustainable?
This material is sourced from natural water bodies and has low persistence or bioaccumulation concern. The main sustainability variables are collection practices, filtration, sterilization, and transport weight.
Is Maris Aqua/Sea Water/Eau De Mer COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic when collected and processed according to the standard’s rules for natural-origin materials. It fits Green Chemistry well as a minimally transformed, non-persistent material, although shipping a water-heavy input is not resource-efficient.
How does Maris Aqua/Sea Water/Eau De Mer work chemically?
This material is an aqueous mixture of dissolved inorganic ions, primarily sodium, chloride, magnesium, calcium, potassium, sulfate, bicarbonate, and trace minerals. It is typically used from low single-digit percentages up to full water-phase replacement, and its electrolyte load can thin or destabilize salt-sensitive thickeners, surfactant systems, and emulsions.
